Precautions
1.Recording Copyright—Unless it’s for personal use only, recording copyrighted material is illegal without the permission of the copyright holder.
2.AC Fuse—The AC fuse inside the unit is not userserviceable. If you cannot turn on the unit, contact your Onkyo dealer.
3.Care—Occasionally you should dust the unit all over with a soft cloth. For stubborn stains, use a soft cloth dampened with a weak solution of mild detergent and water. Dry the unit immediately afterwards with a clean cloth. Don’t use abrasive cloths, thinners, alcohol, or other chemical solvents, because they may damage the finish or remove the panel lettering.
4.Power WARNING
BEFORE PLUGGING IN THE UNIT FOR THE FIRST TIME, READ THE FOLLOWING SECTION CAREFULLY.
AC outlet voltages vary from country to country. Make sure that the voltage in your area meets the voltage requirements printed on the unit’s rear panel (e.g., AC 230 V, 50 Hz or AC 120 V, 60 Hz).
The power cord plug is used to disconnect this unit from the AC power source. Make sure that the plug is readily operable (easily accessible) at all times.
For models with [POWER] button, or with both [POWER] and [ON/STANDBY] buttons: Pressing the [POWER] button to select OFF mode does not fully disconnect from the mains. If you do not intend to use the unit for an extended period, remove the power cord from the AC outlet.
For models with [ON/STANDBY] button only: Pressing the [ON/STANDBY] button to select Standby mode does not fully disconnect from the mains. If you do not intend to use the unit for an extended period, remove the power cord from the AC outlet.
Placement
•The subwoofer cabinet is made out of wood and is therefore sensitive to extreme temperatures and humidity, do not put it in locations subject to direct sunlight or in humid places, such as near an air conditioner, humidifier, bathroom, or kitchen.
•Do not put water or other liquids close to the subwoofer. If liquid is spilled over the subwoofer, the drive units may be damaged.
•Subwoofer should only be placed on sturdy, flat surfaces that are free from vibration. Putting it on uneven or unstable surfaces, where it may fall and cause damage, will affect the sound quality.
•Subwoofer is designed to be used in the upright vertical position only. Do not use it in the horizontal or tilted position.
•If the subwoofer is used near a turntable, CD player or DVD player, howling or slipping of sound may occur. To prevent this, move it away from the turntable, CD player or DVD player, otherwise lower the unit’s output level.
Connection
With other audio-video components, connect the subwoofer’s LINE INPUT to the subwoofer pre out jack of your equipment. Never plug any kind of musical instrument to the subwoofer.
